Add lefty Edgar Olmos to the Mariners' bullpen mix.
The club acquired Olmos, 24, on Wednesday in a waiver claim from Miami just hours prior to the deadline for filing their 40-man roster in advance of the Rule 5 Draft, which is Dec. 11 at the Winter Meetings in San Diego.
Olmos was 3-3 with three saves and a 4.06 ERA this season in 51 minor-league appearances — 18 at Double-A Jacksonville and 33 at Triple-A New Orleans.
He has one option year remaining.
A third-round pick in 2008, Olmos’ only big-league experience came in 2013, when he yielded four earned runs and seven hits in five innings over five outings.
Olmos allowed nine earned runs in 11 innings over nine appearances for Salt River in the just-completed Arizona Fall League. His career record of seven minor-league seasons is 15-37 with a 4.50 ERA in 179 games.
